The first, da marca TS Shara, came with the neutral and ground wires reversed soldiers. A primary error that shows that the company did not even test their products. In taken with proper grounding, the breaker DR realize the leakage current due to the reversal and will turn off. In taken without the ground simply will not work. The TS Shara was contacted, but never answered. I just fixing the problem myself, unsoldering and ressoldando the wires correctly.

The second one, brand Fiolux, knocked the circuit breaker to be plugged in. The problem was a varistor, welded leg to phase bus was touching the ground bus, causing a short. Again: primary error showing that the company did not even tests the products it imports from China and packs. The Fiolux was also contacted, but also did not respond.

Thereafter, I was on the back foot to buy filter lines in Brazil. Trusted brands, as APC are very expensive. Other marks are a lottery, most buy lots of products from China and only put the brand. There are some good, others are bad. Never give to know. At least Line Filter with 5 Taken Universal and Individual Switches It is well tested. For imported equipment, as in the case of my games, is a great option. The same applies to the equipment need not be connected all the time. It's easier to just turn on / off a single switch to stand by removing and replacing sources.
